Title: Improvements in or relating to forked wheel suspension systems for motor cycles
Inventor: WELCH ERNEST GEORGE RISEBOROUG
IPC: B62K25/08
Filed: 1952-02-22
Abstract: 717,259. Spring forks for motor-cycles. NORTON MOTORS, Ltd. May 21, 1953 [Feb. 22, 1952; June 3, 1952] Nos. 4690/52 and 13922/52. Class 136(3) [Also in Group XXXII] A forked wheel-suspension system for motorcycles comprises spaced fork tubes 5 to the lower end of each of which a substantially horizontal wheel supporting arm 7 is pivotally connected, each fork tube housing a load bearing spring 48 and a slidably mounted cylinder 13 for fluid abutting the spring and connected to the wheel arm to be reciprocated upon up-and-down movement of the wheel, and a piston 19 fixed with respect to the fork tubes working in the cylinder to damp this wheel movement. The piston 19 is fixed with respect to the fork tube by a hollow piston rod 18 which forms a reservoir 28 for replenishing the cylinder 13 with damping fluid. The piston 19 has valve controlled passages 22 connecting spaces 25, 23 which are respectively above and below the piston. A valve disc 27 controls an opening between the reservoir in the tube 18 and the space 23. Upon reciprocation of the cylinder 13 liquid is circulated from one side of the piston to the other and thence to the reservoir 28. A circumferential groove 29 in the piston rod tube 18 has a control opening 30 into the reservoir. Towards the end of the downward stroke of the cylinder 13 the groove 29 enters a gland bearing 20 which masks the opening 30 and restricts the flow to that permitted by a sloping flat 31. The wheel arm 7 is pivotally connected to a bracket 6 on the fork tube 5 and to the cylinder 13 by a link 10. A brake mounting plate 45 is pivotally mounted in the wheel axle 41 and is pivotally connected to a split clamp 47 around the fork tube 5 by a link 46.

Patent GB-1347191-A (GB)
Title: Starting arrangements for electric motors
IPC: H02P1/26
Filed: 1972-02-02
Abstract: 1347191 Control of A.C. motors SIEMENS AG 2 Feb 1972 [3 Feb 1971] 4861/72 Heading H2J A single phase asynchronous motor (not shown) is supplied via a terminal 3 and changeover switch U which is connected to an A.C. mains 7 during motor starting and to a mainsfed inverter 4 controlled by a pulse generator 5 during subsequent running, the change-over being effected after the starting period is completed and there is phase equality between the output voltage of the inverter and that of the mains. The latter condition is detected by a phase comparator 12 which controls a device 11 actuating the switch U, a switch D also being controlled by comparator 12 to connect a mainsfed synchronizing device 13 to the pulse generator 5 to maintain phase equality once it has been detected. In a simple arrangement, the inverter is constantly synchronized with the mains and change-over of the switch U is determined by a time delay element in the device 11, which element is started when the motor is connected to terminal 3 and causes operation of switch U after an adjustable time corresponding to the starting period. It is preferred, however, to use a threshold value circuit 14 sensing motor current and starting the delay element when the current exceeds a predetermined value. If the current falls below this value, for example when the motor is switched off, the switch U automatically changes over to reconnect the motor to the mains. The circuit 14 can have two threshold values to permit the delay element to be omitted, since the fall of current below the upper threshold value can be used to cause device 11 to change over the switch U. A similar operation can be achieved by using a single response threshold circuit. To avoid constant synchronization of the inverter with the mains, this may be effected only during starting by using a two-threshold value circuit which actuates the comparator 12 when the motor is switched on. When synchronization is effected, the comparator 12 puts the device 11 into a state ready to actuate switch U, this operation being effected when the current falls below the upper threshold value. Simultaneously, a time delay element is operated to block the synchronizing pulses when changeover has been completed. An AND gate may be included to ensure that mal-operation is not caused by the motor reaching its normal running speed before synchronization is effected. In a final embodiment, the threshold value circuit has one response value which, when exceeded, actuates the comparator 12 whose closure of switch D also starts a time delay element in the device 11 to cause the latter to subsequently change-over the switch U, synchronization being discontinued after a further delay following the change-over. Modification of the circuit may be made to start a three phase motor with a shortcircuited secondary winding.

Abstract: 697,606. Centrifugal separators. AKTIEBOLAGET SEPARATOR. March 2, 1950 [March 2, 1949], No. 5320/50. Class 23 In the bowl of a centrifugal separator for separating solid particles from a liquid or sorting solid particles suspended in a liquid and having one or more annular channels 4a, 4b arranged between the separating space 2a and outlets 7 for separated solid particles, the concentrated suspension of solid particles flowing outwardly along the channels is met by inwardly flowing washing liquid, the inner length of the inner walls of the channels being smooth and unobstructed and the supply of washing liquid being such that turbulence, resultant upon the diflerence in rotational velocities of the walls of the channels and of the inflowing washing liquid, develops in the channels and this turbulence facilitates the separation or the sorting. Starch and gluten particles suspended in a liquid are supplied to the interior of the bowl by passages 1 in a disc 10, and washing liquid is directed to the channels by passages 9, annular chamber 11 and holes 5 in the disc. The starch particles with some washing liquid are discharged through the outlets 7 and the gluten particles with the rest of the liquids flow inwardly and are discharged. The holes 5 may discharge in the direction of the bowl's rotation to increase the turbulence, and the outer boundary of the channels may have shallow grooves which rotate the outflowing concentrated suspension at the speed of the bowl. Specification 645,463 is referred to.

Title: Improvements in or relating to couplings for model railway vehicles
Filed: 1942-04-22
Abstract: 556,938. Toy railways; couplings. PINDER, T. April 22, 1942, No. 5374. [Class 132 (iii)] A coupling for model railway vehicles is provided with a platform between the tailstock at the inner end and the ramp at the outer end and a freely pivotal lever is mounted adjacent to the platform for raising the coupling link of the adjacent vehicle clear of the platform and inclined plane when it is desired that the vehicles be uncoupled. Lever 1, Fig. 1, normally occupies its clockwise position, but has an alternate, counter-clockwise position of equilibrium. Coupling link hook 11 carried by another vehicle rides over nose 3 and along platform 4 to effect coupling if the motion is gentle. To uncouple, the vehicles are backed violently so that link 11 jolts lever 1 into the position shown in dotted lines and when the vehicles are drawn apart again, link 11 rides up arm 6 and over the top of nose 3, restoring lever 1 to original position. In a modification, Fig. 3, an inverted hook 9 embraces lever 1 and is momentarily lifted without disturbing lever 1 when link 11 is engaged. When link 11 is jammed against lever 1, both the lever and the inverted hook are rocked into the position shown in dotted lines, whereupon link 11 can be withdrawn gently, restoring the lever after it passes the end of the inverted hook. A stop 10 limits the clockwise movement of lever 1. In Fig. 6, hook 9 is shown as integral with lever 1. Each vehicle carries a coupler and link at each end.
